How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with the package name, latest version string, SPDX license identifier, and total dependency count for the specified npm or PyPI package.
Example use cases
Check npm package license compliance
“What license does the 'lodash' npm package use, and how many dependencies does it have? I need to check if it's safe to include in our project.”
Verify PyPI package version before install
“Can you check what the current version of the 'requests' package is on PyPI?”
Audit dependency footprint of a library
“How many dependencies does 'axios' have on npm? I'm trying to evaluate how heavyweight it is before adding it to our codebase.”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/package?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, structured metadata (version, license, dependency count) for a specific npm or PyPI package without scraping registry pages manually. Prefer it over raw web searches when you need machine-readable output for compliance checks, dependency audits, or version pinning decisions.
Side effects
- Package not found in the specified ecosystem — returns error or empty result
- Invalid ecosystem value (not 'npm' or 'pypi') — schema validation error
- Missing required 'package' query parameter — request rejected
- Network or upstream registry timeout — may return partial or error response
- Payment not completed (x402) — request blocked before execution
